The shrimp Rimicaris exoculata swarms around hydrothermal black smoker chimneys at most vent sites along the Mid-Atlantic Ridge. This species maintains close proximity to the hydrothermal fluid, where temperatures can reach 350 degrees C and steep thermal and chemical gradients are expected. We performed in vivo experiments in pressurized aquaria to determine the upper thermal limit [critical t...

Mycobacteria in drinking water and the of swimming pools, whirlpools, hydrotherapy facilities aquaria contribute significantly to human exposure triggers immune regulated chronic inflammatory autoimmune diseases. Technological elements distribution systems, especially their inner surface, taps, shower heads blind spots where sediments settle, affect number mycobacteria water. The review present...

In this study, the karyotypic characteristics of Chondrostoma regium (Heckel, 1843) have been investigated. Fish samples were caught from Karasu River (Euphrates Basin) with fishing net. The live fish transported to laboratory and kept in aerated aquaria before analyses. karyotype analysis was performed kidney gill epithelium cells. It determined that C. had 2n=50 chromosomes. detail, formula a...

An experiment was conducted in glass aquaria to study the growth performance of common carp fry fed on four different feeds for 120 days. Four different feed ingredients used were fish meal + soybean+ Groundnut cake+ rice bran +wheat flour, fish meal + Groundnut cake + rice bran + wheat flour, soybean + Groundnut cake + rice bran + wheat flour and commercial cattle feed. The feed was supplied @...

Knowledge on seahorses is generally scarce but has been increasing in recent years due to their conservation status. Seahorse culture is a quite recent activity in the field of marine aquaculture in most countries attempting it, and captive breeding techniques are available only for some species. With the aim of contributing to the development of breeding in captivity for conservative purposes,...

This study was conducted to estimate the prevalence, mean abundance, and intensity of common protozoa infection on Mediterranean horse macherel (Trachurus mediterraneus) from Zliten coast, Libya. A total 32 specimens species were collected randomly. The fish transported immediately alive laboratory in Department Fish Biology Culture, College Marine Resources, Asmarya University, where they main...

Abstract During the Deepwater Horizon (DwH) oil spill, an excessive production of marine snow was observed, and it estimated that as much 14% transferred to ocean floor by MOSSFA (Marine Oil Snow Sedimentation Flocculent Accumulation). is important pathway transferring floor. We performed experiments at laboratory scale in 15 aquaria, representing 5 exposures with or without oil, only controls ...
